# Question:Class 3 Error Report no. 2005-08 states that the temperature is evaluated "elsewhere within the element". Does this mean that the temperature is still being evaluated at the centroid, at a different integration point, or what?Answer:The error only affects the coefficient of thermal expansion (CTE), the instantaneous coefficient of thermal expansion.PLANE42 has 4 integration points. The CTE using the correct temperature at point 1 is called C1, point 2 is C2, etc. Also the CTE using the correct temperature for the element centroid, is CC. In Release 9.0, the CTE using the temperature computed at point 1 is called A1, point 2 is A2, etc. Thus, the erroneous usages may be summarized:A1 = CCA2 = C1A3 = C2A4 = C3In other words, it's one step behind.Desired, of course, is;A1 = C1A2 = C2A3 = C3A4 = C4which is what is in version 10.0.
